抄録

The surfaces of sintered carbide alloys eroded by the electrical-discharge machining were examined by X-ray diffraction.<BR>The results obtained were as follows:<BR>(1) In WC-Co series, the carbide WC, which has a hexagonal lattice in normal state, was transformed to a close-packed structure (either face-centered-cubic or hexagonal-close-packed) in the eroded surfaces.<BR>(2) In WC-TiC-Co series, the continuous series of solid solution of WC (abnormal face-centered-cubic structure above mentioned) and TiC (face-centered-cubic structure originally) were discovered.
